T 0' all whom it may concern Be it known that 1, JAMES DAVIS, a citizen of the United States, residing at St. James, in the county of Phelps, Stat'eof Missouri, have invented certain new and useful Improvements in Brake-Shoe Holders, and I do hereby declare the following to bea full, clear, and exact description of the invention, such 'as will' enable others skilled in .the art tO Wl1lCl1 1t apperta ns, to-

makejand use the same This invention relates to new and useful improvements in brakes for, vehicles and is. particularly directed tov the provision of means associated Wltli'tlltt type of brake 111-,

eluding a transverse brake beam, whereby shoes'may be readily secured to ordetached from the beam. 7 v

It is the object of the present invention to provide such means for securing brakesho'jes to a brake beam, which isreadily operable and does not require the use of a special type of shoe, and which is adjustable in nature to adapt it to shoe members-of varying width. J .1

It is further the obj ectto provide such a securing means provided with a permanently connect ed handle member for operating the same to securing or released position and which has said handle member so associated therewith that when not in use,

itmay be positioned to lie along the beam..

With the above objects and advantages in view, the invention resides more particularly in the novel combination, formation and arrangement of parts more fully hereinafter described and particularly pointed out in the appended claims.

Reference is had to the accompanying drawings, wherein similar characters of reference designate corresponding parts throughout the several views and in which:

Figure 1 is a top plan view of the improved shoe seouring means applied to a brake beam, Fig. 2 is a sideview thereof with parts broken away, Fig. 3 is a view looking toward the other side of the device with the handle or actuating member illustrated in full lines in an inoperative position and in dotted lines in operative position, Fig. 4- is a sectional view taken longitudinally on the line H of Fig. 1. Fig. 5 is a transverse sectional view taken on the line 55 of Fig. 1, and Fig. 6 is a sectionalview taken transversely on the line 6-6 of Fig. 2.

- Referring now Imore particularly to the accompanying drawings, the improved def straps T disposed at the sides of the beam, 1

these straps being secured to the beam by screws B orthe lilie one, screw .8 at the forward sidejof the beam, also serving to hold abowed, metallic plate .9 which extends transyersely of thebeam' and-is adaptedto be engaged by the brakeshoebloclr10, this block comprising merely a rectangular piece of wood of an approximatewidthto properlyengagezthe wheel for braking action. For, securely gripping and holding this block the forward ends'of the shafts6 are squ'aredmnd passed through eccentrically, disposedv slots 11 formed in the webportions 12 of clamping cylinders 13, and wedge members 1% are also engaged in; the said slots to bind; the cylinders on the shafts. This is a desired structure, although it will be understood? that any propermeans for eccentrically securingzthe shafts may be employed. The outer peripheries of the cylinders are providedwith series of teeth 15' a and thus when the shafts 6 are rotated, the cylinders move together to engage their squared rear end of the otherrshaft 6 and extending upwardly, these arms having their free ends connected by a substantially Z- shaped link 18 the ends of which are laterally directed at 19 and pivotally passed I through the arms. A handle lever for actuating this structure is providedwhich comprises aibar 20 formed in one end with a slot2l loosely receiving that shaft 6 carrying the upstanding arm 17, and formed in its .:.intermediate portion with an angular slot 22 adapted to engage with theadjacent portion 19of the-link in such manner that by rocking'the lever, the shafts will be rocked. This 'lever may be readily disengaged from the portion 19 of the link and swung to lie along the beam, it. being held against downward swinging movement byengagement with the Shaft structure other than that to which it is attached. 7

The shafts are normally locked against relative rotation by means of a bar 28 pivoted on one of the shafts 6- and provided with a longitudinal slot 24 slidably receiv from the spirit of the invention. For instance, the clamping cylinders described form substantially cams on the shafts, and any desired cams may be used.

l/Vhat is claimed is:

1. A securing means of the class described comprising the combination with a brake beam of a pair of shafts transversely carried thereby, cam members on said shafts, means for rotating said shafts in opposite directions and means for locking said shaftsagainst rotation. V

2. A'securing means of the class described comprising the combination with a brake beam of a pair of shafts transversely carried thereby, cam members on said shafts, arms carried by the shafts, a handle member pivoted on one of the shaftsand detachably engageable With the free portion of one of the arms and a link connection between the arms. p

3. A securing means of the class described comprising the combination With a brake beam of a pair of shafts transversely carried thereby, cam members on said shafts, arms carried by the shafts, a link connecting said arms, a member secured to one of the shafts and slidably engaging the-free end of the arm of the'other shaft and means for looking said arm against sliding movement With relation to the member.

1. A securing means of the class described comprising the combination with a brake beam of'a pair of shafts transversely carriedthereby, cam members on said shafts, arms extending in opposite directions from said shafts, a link having its end portions laterally directed and pivotally engaged through the arms, a member secured on one of the shafts and provided with a longitudinal slot slidably receiving that laterally directed end of the link engaged With the arm of the other shaft,and a thumb nut on said end for clamping the arm and member together to lock the shafts against relative rotation.

In testimony Wl16TOf,'I afix my signature, in the presenceof two Witnesses.
